To all whom it may concern: 1

Be it known that I, FELIX DAUM, chemist,-

residin at 46, Kaiserstrasse, Mainz, in the Grand uchy di Hesse,Germany, have in vented new and useful Im rovements in Soap-MoldingMachines, of W 'ch the followin is a specification.

his invention relates to a soap-molding machine, and has for its objectto charge the liquid soap into molds to cool the same and to effect itssolidification, the bars or cakes of soap thus produced being thenremoved either by hand or otherwise. The machine is so arranged as to becapable of continuous working.

The machine consists for this purpose of a hollow rotating drum suitablmade of sheetiron, on the periphery of w 'ch areformed "box-likerecesses, the ,size and configuration of which correspond to the desiredform of the soap-bars or tablets to be produced. The

- interior of the drum is cooled by means of bottoms, to which areattached rods extendt e mo ds of the drum are open at t water, cold air,carbon dioxid, or the like, and the drum is made to revolve partlywithinan external coolin -jacket. The liquid soa passes from a ta arranedv onthe top of till they pass round underneath, and as the drumtravels round the soap-is solidified by the coolin action, so that theformed bars or tablets w' 1 either drop out of themselves at that partof the machine where the drum is not inclosed in the jacket or they areremoved by hand or by-'mechanical means. For removing the bars ortablets mechanically the molds may be provided with movable ing into thedrum, where they are. acted upon by a fixed cam or the like, so as topush the .bottoms outward, and :thus force the bars or tablets out ofthe molds. The mechanical e'ectin in which case the still liquid soap isprevented from runnin out b means of metal plates a ainst which t e en sof the drum revolve. -T ese lates have openings at a suitable oint, tough which a plug, moved'either by' and or mechamcall is made to enterthe mold, so as to eject t e solidified bars or tablets irom the same.

On the accompanying drawings is shown a soap-niolding machineconstructed according to my invention.

e drum into the molds o the latter asdevice can also be so' arrangedthat asides,

Figure 1 shows a longitudinal section of the machine on line 1 1, Fig.2. Fig. 2 is a section online 2 2, Fig.1. Fig. 3 is a side View, part1in section, of a modified construction o the machine with a mechanical ais the hollow drum, in the 'peripherv of whichai'e formed the recesses12, constituting molds for receiving theliquid soap. The inter-ior c ofthe drum and the sides and bottoms ofthe molds are cooled by means ofwater, cold air, carbon dioxid, or the like, which may be suitablysupplied through the hollow shaft (1 and branch tubes 0, Fig; 2. Thegreater part of the drum (L outside the tanki is surro'undedby acooling-j acket f, to which water or other cooling medium is suppliedthrough the pipe 9 and whence it is discharged through the pipe h. Abovethe drum is arranged the tank i for the liquid soap. From this tank theliquid soap flows into the moldsas they ass under it, and it thensolidifies as the mo ds pass round to the uncovered part of thedrum,where the bars or tablets either fallonto a table or they are Accordingto the.

.3. the

molds b-are provided with piston-1i e bottoms it, having rods Z, thatextend inward in the drum. Each mold is preferably rovided with tworods, one at each end. T ese rods slide in contact with a fixed cam orcams m of such ashape that the bottoms 7c remain in position at theinner'ends of the molds during the greater ortion of a revolution, butare protruded w en the molds arrive at the part where the drum isuncovered, so that .the soap bars or tablets are ejected at that point.

In the arrangement at Fig. 4 the molds b are open at the-ends. Theliquidsoap is prevented from running out by means of fixed platesn atthe ends of the drum, between which the latter revolvesl At a suitablepoint the lates n have openings 0, through which, a p ug p can enter themolds at one plug 72 is guided in arms 9 on the framing of w the machineand is either actuated by hand or by any suitable mechanical devices.

. Now What I claim, anddesir'e to secure by V Letters Patent, is thefollowing:

1. In a machine for effecting the solidification of lieuid soap in moldsthe combination of a revo ving drum with recesses formed at v theperiphery thereof and constituting molds for the soap, a tank forreceiving the liquid soa and supplyingit to the molds, a jacket incuding the tank, artially surrounding the drum, and means or cooling thesides and bottoms of the molds-during -2. In a machine for efie'ctingthe solidification of li uid soap in molds the combination of a revoving drum with recesses formed at the periphery thereof and constitutingmolds for the soap, a tank for receiving the li uid soap and supplyingit to the molds as t ey pass under it, a jacket .including the tank,

" partiallysurrounding the drum, and means or cooling the sides andbottoms of the molds during their revolution, substantially asdescribed.

3. In a machine for effecting the solidification of li uid soapinmoldsthe combination their revolu tion, substantially as described.

molds applied to the interior and exterior of the drum, substantiallyasdescribed.

4. In a machine for effecting the solidifica inc uding the tank,partially surrounding the drum, means for'cooling the sides-and bottoms.of the molds during their revolution,

and means for mechanically removing the solidified soap from themachine, substanv tially as described.

5. In a machine for effecting the solidification of H uid soap in moldsthe combination of a revo ving drum with recesses formed at theperiphery thereof and constituting molds for the soap, a tank forreceivin' the li uid soap and supplying it to the mo ds as t ey passunder it, a cooling device for the molds applied to the interior of thedrum, and a cooling-jacket arranged around the drum and open at one sidefor the purpose .of removing the solidified soap, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
